How Hot Would a Light Saber Really Be?
Ok, so this is an April Fools joke.
But it is also an interesting physics question. If there really was a such thing as a light saber, how hot would it be?
I would suppose that it would be not very hot.
Simple explanation:
We associate light and heat becuase of two things: The sun and incandescent lighting.
The heat from the sun is unrelated to the visible light spectrum, and is instaed a factor of it's infrared spectrum, which we cannot see.
The heat from an incandescent light is a by product of exciting the filament enough to have it emit photons.
Example in the opposite direction - laser pointers.
Ever aimed the beam from a laser pointer at your skin? Did you feel anything? Light does not equal heat.
So, a beam of focused, concentrated light, manipulated by the mind of a Jedi Master would very likely have no heat or coolness associated with it at all.
Probably would still hurt like hell to get sliced with one.
